How does keyboard communicate with computer
Laptops use internal connectors. Regardless of which type of connector is used, the cable must carry power to the keyboard, and it must carry signals from the keyboard back to the computer. Wireless keyboards, on the other hand, connect to the computer through infrared IR , radio frequency RF or Bluetooth connections. IR and RF connections are similar to what you'd find in a remote control.
Regardless of which sort of signal they use, wireless keyboards require a receiver , either built in or plugged in to the USB port, to communicate with the computer. Since they don't have a physical connection to the computer, wireless keyboards have an AC power connection or use batteries for power. Whether it's through a cable or wireless, the signal from the keyboard is monitored by the computer's keyboard controller.
